The term rollover is used exclusively for FX positions. Rollover fees are charged on FX positions held overnight. Rollover is calculated at 15:00 GMT on weekdays, weekend rollovers are calculated on Wednesday. However, please note that the rollover calculation is based on the balance of the previous (closed) trading day.
The rollover is calculated as (current notional value x * rate * days) / 360.
You can always check the rollover and overnight fees that may be applicable to your account in your clients area on exante.eu:
